LUNG INJURY/OCCUPATIONAL INJURY Flashcards
What is sepsis a result of?
Infection that gets so advanced that it causes an inflammatory response that affects the entire body.
OR toxins which are released into the body as a result of biproduct of the infection causing tissue damage to the lungs.
What is the most devastating response which can cause multi-organ failure?
Inflammatory response
How does inflammatory respond to the infection? How does the brain respond? What is it called when it affects the blood vessels going to the lungs? What does typically end up causing in the lungs?
It releases chemical that destroy tissue.
When this happens in the brain you are less responsive.
When it affects the blood vessels going to the lungs it’s commonly known as ARDS
Causing massive pulmonary edema in the lungs.
Is lactacte important? What is the relation to lactate and mortality rate?
Yes, the higher the lactate is the higher the mortality rate is.
What does a high lactate marker indicate?
There is hypoxia at a cellular level.
What is not chemically reactive and not dissolved by water and is essentially what asbestos is made of?
Silicone Dioxide, it is an incredible stable substance.
What is the consistency and structure of Abestos? What makes it different and easy to make its way down the respiratory tract?
Sand, dirt, and tiny needle-like structures
The shape of it is what makes it different.
The tiny needle-like structures are so fine that they find their way down to the respiratory tract.
What happens once Asbestos has made its way down to the respiratory tract and into the lungs? What attempt to break it down and what does it cause instead?
The body cannot break them down, macrophages try to break down the asbestos molecules but instead cause inflammation as it is never able to.
What indicated the worsening effects of the infection through the patient’s body with sepsis?
Respiratory culture
For every hour which passes without giving a patient with sepsis antibiotics what is the relationship increase in mortality rate?
10% for every hour
What does sepsis cause in the chemical release?
It causes the release of chemicals throughtou the body that damage the immune system such as the endothelial cells, capillaries, arterioles, venioles.
This in turn leaks fluid into brain, kidneys, lungs causing ARDS.
What can sepsis also cause?
ARDS & AKI
What is the hemodynamic effect of sepsis?
It dilates the blood vessels, which increases blood volume and causes blood leakage, which decreases blood volume, and demand for blood increases and goes to the lungs.
What are the treatments for sepsis?
Antibiotics and diuretics
How far can Abestos reach? How does it affect the state of the lungs?
It reaches the lower lobes
Causes scarring to the lungs and reduces lung ability to receive oxygen
How do macrophages in the lungs attempt to treat the lung from Abestos?
They try to engulf the small bits of silicone dioxide to help treat the lung.
What is the blood pressure manifestation of sepsis? And why?
Low blood pressure due to inflammation causing vasodilation which requires more blood supply to the heart.
With ARDS secondary to sepsis what is our main priority?
Keeping the patient alive for enough time to allow the body to heal itself.
